“I first met Greg at his all-day, hands-on seminar at SXSW 2013 promoting “Android Design Patterns.” While many experts speak in vague generalities and buzzwords, within minutes it was apparent that Greg had a true mastery of his subject. His seminars, and his books, are for people who want straight talk and solid, detailed visual examples of mobile UI best practices.

There is an anecdote from that event which, to me, illustrated both Greg’s outstanding personal character and his genuine interest in expanding his own knowledge: At one point, not knowing I was in the audience, he showed one of my designs as an example of ‘asking for unnecessary information.” At the next break, I stopped and introduced myself, and explained why that particular form field was indeed important as it impacted the prices a customer would see. Rather than just smiling and dismissing that information as most speakers would have done, when the session restarted he asked for the whole room’s attention. He then told everyone about our conversation and even went back to that slide to show the visual in question — and emphasized why it was important that all designers fully understand business requirements before passing judgements. In my experience, only a small handful of authors would have done that.

Therefore, if you are looking for an author/speaker for internal staff training, consulting, or upcoming UX event, I recommend Greg and his books very highly. He is able to effectively and rapidly communicate real world UI solutions that can immediately improve any mobile application design.” -Marti Gold, UX Director, North America at W3 Americas
